摘要
快速真实地模拟树在风中的摇曳一直是计算机图形学中的一个挑战性问题,作为自然场景的重要组成部分,树木的真实感模拟也得到人们的广泛重视。树木种类繁多,形态各异,复杂的结构使其无论在造形、存储还是在绘制上都存在着相当的困难。大多数园林设计软件很难构建模型参数可变的三维树。研究了一种简易的基于分形递归算法的建模方法,利用过程参数控制树的摇曳,使模型的真实感更强,变形计算更容易,得到了令人满意的实验效果。
Fast and realistically simulating the tree swaying in wind is still a challenge topic in computer graphics. As a very important part of natural scenery, realistic rendering of trees has attracted much attention. Trees have various types with different shapes and due to their complex structures, realistic modelings, rendering and storage of trees are always a tedious task. Constructing a 3D tree model which owns alterable parameters is difficult for most of garden design software. A simple generation method based on fractal recursion algorithm is researched. Having utilized process parameters to control the sway of tree, the model of tree was more realistic and deformation computation is more easier. Experimental results are satisfactory.
